TypeError: Module specifier, 'application' does not start with "/", "./", or "../"

[gabrieelgomez]

Hello! I got this error while starting my recent rails new app on 7.0.4.2 and ruby 3.2.1

I just did a hello world in the root path and when I see the logs I get this

Gemfile

gem "importmap-rails"

config/importmap.rb

pin "application", preload: true
pin "@hotwired/turbo-rails", to: "turbo.min.js", preload: true
pin "@hotwired/stimulus", to: "stimulus.min.js", preload: true
pin "@hotwired/stimulus-loading", to: "stimulus-loading.js", preload: true
pin_all_from "app/javascript/controllers", under: "controllers"

This can be ignored as the next line says in the console output

importmap-rails/app/assets/javascripts/es-module-shims.js

Lines 31 to 33 in 33e26bc

	const onpolyfill = esmsInitOptions.onpolyfill ? globalHook(esmsInitOptions.onpolyfill) : () => {
	console.log('%c^^ Module TypeError above is polyfilled and can be ignored ^^', 'font-weight:900;color:#391');
	};

What browser do you use and which version? Vide https://caniuse.com/?search=importmap

@gabrieelgomez Since this is expected behavior can you close the issue?

Yup. Can confirm nothing breaks.
